Abstract
The utility model relates to a portable operating table of mesa, including the bedstead seat, can with the movable support of bedstead seat relative movement, the rack is fixed on movable support, is equipped with a transmission shaft on the bedstead seat, is fixed with a worm in the one end of transmission shaft, and the other end is fixed with a crank, is equipped with the gear with worm engaged with, and the gear passes through the clutch and links to each other with another gear, and another gear meshes with the rack mutually, and the movable support superscript has the scale. The structure is simple; the worm drive has the auto-lock performance, guarantees the stationary state of operation mesa under the condition of not shaking, realizes deciliter through the clutch, can realize the translation that the crank drove the mesa when closing, and movable support and bedstead seat separation when separating, but the operator quick travel movable support realize the translation of mesa, have the scale on the movable support, but accurate control mesa translation volume.
Description
One, technical field
This utility model relates to operating-table, particularly operation table with movable table top.
Two, background technology
Operation relatives of Taiwan compatriots living on the Mainland medical device product is implemented operations such as surgery such as head, neck, splanchnocoel, perineum and extremity and department of obstetrics and gynecology, department of eye, orthopaedics for hospital operating room.The table top translation functions can be in operation process and the supporting use of C type arm, and all tools all are motor-driven operating tables with the operating-table of table top translation functions, and by the motor transmission, cost is big, the price height.Patent 03232554 discloses " a kind of parallel-moving type operation table ", be provided with a screw mandrel in the inside of the external cover of bed, one end of screw mandrel connects first gear, first gear and second gears engaged, second gear is connected with handle, the other end of screw mandrel and swivel nut one end socket, the swivel nut other end is fixedlyed connected with a guide rail, and the teeth angle of first gear and second gear is designed to 45 degree.Make gear rotation by shaking handle, allow screw mandrel and swivel nut relative motion, and transfer rectilinear motion to.Its complex structure, the transmission chain length can not realize quick translation.
Three, summary of the invention
The purpose of this utility model is at above-mentioned the problems of the prior art, and a kind of operation table with movable table top is provided.
The purpose of this utility model is to realize like this, a kind of operation table with movable table top comprises the bedstead seat, the travel(l)ing rest that can relatively move with the bedstead seat, tooth bar is fixed on the travel(l)ing rest, be provided with a power transmission shaft on the bedstead seat, be fixed with a worm screw at an end of power transmission shaft, the other end is fixed with a crank, be provided with the gear that is meshed with worm screw, gear links to each other with another gear by clutch, and another wheel and rack is meshed, and travel(l)ing rest is marked with scale.
The translation that the beneficial effects of the utility model travel(l)ing rest drives the operating-table table top is to drive the worm screw rotation by crank, and a worm screw and a gears engaged are connected with another gear by clutch, and the tooth bar moving linearly drives the bed surface translation, and it is simple in structure; Worm-drive has self-locking property, guarantees at the stationary state that does not shake operation table top under the situation; Helical gear and helical rack transmission guarantee the stationarity in the transmission process.Helical gear A and helical gear B realize deciliter that by clutch can realize when closing that crank drives the translation of table top, travel(l)ing rest separates with the bedstead seat in the time of separately, but operator's fast moving travel(l)ing rest, the translation of realization table top; Scale is arranged on the travel(l)ing rest, can accurately control the table top translational movement.
Four, description of drawings
Fig. 1 is this utility model structure diagram.
Fig. 2 is this utility model lateral plan
Among the figure: 1 crank, 2 power transmission shafts, 3 tooth bars, 4 gear A, 5 worm screws, 6 travel(l)ing rests, 7 bedstead seats, 8 gear B, 9 clutches
Five, the specific embodiment
Below in conjunction with accompanying drawing, this utility model specific embodiment is described in further detail:
A kind of operation table with movable table top among Fig. 1, tooth bar 3 is fixed on travel(l)ing rest 6, bedstead seat 7 is fixed with a power transmission shaft 2, power transmission shaft 2 one ends are fixed with a crank 1, the other end is fixed with a worm screw 5, travel(l)ing rest is marked with scale, and crank 1 rotates can indicate bed surface displacement, the gear A 4 that matches with worm screw 5.
Clutch 9 one ends link to each other with a gear B 8 with the helical gear A4 other end among Fig. 2, and helical gear B8 matches with tooth bar 3.
When clutch 9 closes, it is by rotating crank 1 that travel(l)ing rest 6 moves relative to bedstead seat 7, rotating drive shaft 2, worm screw 5, gear A 4, clutch 9, gear B 8 and tooth bar 3 realize that worm-drive has auto-lock function, makes travel(l)ing rest 6 relative bedstead seat 7 relative motioies; When clutch 9 separated, worm-drive was inoperative, and the operator can directly promote travel(l)ing rest 6, realized the quick translation of travel(l)ing rest 6.
Claims (2)
1, a kind of operation table with movable table top, comprise the bedstead seat, the travel(l)ing rest that can relatively move with the bedstead seat, be fixed on the operation table top on the travel(l)ing rest, it is characterized in that: be fixed with tooth bar on the described travel(l)ing rest, be provided with a power transmission shaft at described bedstead seat, end at described power transmission shaft is fixed with a worm screw, the other end is fixed with a crank, be provided with the gear that is meshed with described worm screw, described gear links to each other with another gear by clutch, and described another gear matches with described tooth bar.
2, operation table with movable table top according to claim 1 is characterized in that: described travel(l)ing rest is marked with scale.
